    Abstract: Disclosed is a thermoplastic resin foam which is obtained by subjecting a thermoplastic resin composition containing a thermoplastic elastomer and an active-energy-ray-curable resin to foam molding to give a foamed structure, and irradiating the foamed structure with an active energy ray to allow the active-energy-ray-curable resin to form a cross-linked structure in the foamed structure. Also disclosed is a thermoplastic resin foam which is obtained by subjecting a thermoplastic resin composition containing a thermoplastic elastomer, an active-energy-ray-curable resin, and a thermal cross-linking agent to foam molding to give a foamed structure, irradiating the foamed structure with an active energy ray to allow the active-energy-ray-curable resin to form a cross-linked structure in the foamed structure, and heating the resulting foamed structure bearing the cross-linked structure to thereby allow the thermal cross-linking agent to form another cross-linked structure in the foamed structure.

    Abstract: Scaffold comprises a polymer defining macropores and comprising hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, which is crosslinked through the self-crosslinkable group. The macropores have an average pore size larger than 50 microns and are at least partially interconnected. In one method, bicontinuous emulsion comprising a continuous aqueous phase and a continuous polymer phase is formed. The polymer phase comprises hydroxypropylcellulose partially substituted by a substituent comprising a self-crosslinkable group, and is crosslinked through the self-crosslinkable group to form a polymer defining at least partially interconnected pores. In another method, phase separation is induced in a solution comprising a polymer precursor and water to form a bicontinuous emulsion comprising a continuous polymer phase and a continuous aqueous phase. The polymer precursor comprises a self-crosslinkable group and is crosslinked through the self-crosslinkable group in the emulsion to form a polymer defining at least partially interconnected macropores.
